Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If abstract results of different complex intersections are used for navigation information generation, then the navigation process is simplified, but the discrimination degree for complex intersections deteriorates
Solution Approach 1:
The patent segments complex intersections into multiple sub-intersections based on geometric features and topological relationships. Each sub-intersection is analyzed separately to generate specific navigation information, thereby maintaining discrimination degree while simplifying the overall navigation process through structured breakdown of complex scenarios.
Solution Approach 2:
The patent applies local quality by generating differentiated navigation information for different types of complex intersections based on their specific geometric and topological characteristics. Instead of using uniform abstract results, the system tailors navigation instructions to the local features of each intersection type, improving discrimination while maintaining process efficiency.
2Device complexity
If uniform navigation information is generated for different complex intersections, then the system complexity is reduced, but the navigation accuracy deteriorates
Solution Approach 1:
The system segments the navigation information generation process into standardized modules for acquiring intersection information, determining geometric features, analyzing topological relationships, and generating navigation instructions. This modular segmentation maintains manageable system complexity while enabling accurate, differentiated navigation information for various complex intersection types.
Solution Approach 2:
The patent changes key parameters such as geometric features (intersection angles, road widths) and topological relationships (connection patterns, traffic flow directions) to generate differentiated navigation information. By systematically varying these parameters based on intersection characteristics, the system maintains accuracy without requiring excessive complexity.
